Replace Travis CI w/ GitHub Actions CI

There are a few things that had to happen: - Had to add more modern rubies to the CI configuration. - Had to tweak versions to use the latest patch levels and bump jruby GitHub Actions doesn't have some of the versions that we were using in Travis CI. - Update README to point to GitHub Actions instead of Travis CI

 In [Erik Michaels-Ober](https://github.com/sferik)'s great talk, 'Writing Fast Ruby': [Video @ Baruco 2014](https://www.youtube.com/watch?v=fGFM_UrSp70), [Slide](https://speakerdeck.com/sferik/writing-fast-ruby), he presented us with many idioms that lead to faster running Ruby code. He inspired me to document these to let more people know. I try to link to real commits so people can see that this can really have benefits in the real world. **This does not mean you can always blindly replace one with another. It depends on the context (e.g. `gsub` versus `tr`). Friendly reminder: Use with caution!**
